To find the turbulence spectrum \(E(k)\) , as noted above, it is necessary to integrate the expression \(k^2\epsilon _k\)  over the entire solid angle. Figure REF  shows the result of this averaging over the angle for the moment of time corresponding to the quasi-stationary state. It is clearly seen from Fig. REF  that in the regime of quasi-stationary chaotic motion, the spectrum of \(E(k)\)  acquires a power law behavior. Recall that the inertial interval was \(k \in [6, 100]\) . As can be seen from Fig. REF , there are two regions with different behavior of the spectrum in the inertial interval. In the region of large wave numbers, the spectrum of weak acoustic turbulence coincides with the Zakharov-Sagdeev spectrum (REF ) with high accuracy, and in the long-wave region, deviations from this spectrum are observed, which, in our opinion, arise due to jets, whose role is significant at small \(k\) . It should be noted that similar large deviations of an oscillatory nature from the Zakharov-Sagdeev spectrum were observed numerically when simulating the condensate in the framework of the Gross-Pitaevskii equation [1]}. In our opinion, these deviations can be related to the anisotropy caused by the presence of jets. No jets were found in the experiment [1]}. In our numerical experiment, the spectral energy density \(\epsilon _k\)  approaches an isotropic distribution in the region of large \(k\)  as it follows from Fig. REF  and REF . The dispersion \((ka)^2\)  changes from \(10^{-3}\)  to \(10^{-1}\)  in this region, i.e., remains weak. These two factors contribute to the formation of the Zakharov-Sagdeev spectrum. It should be specially emphasized that the found turbulence spectrum is far from the Kadomtsev-Petviashvili spectrum \(E_{KP}\propto k^{-2}\)  [3]} related to the dispersionless limit (\(a=0\) ).
